  1. Can we use the OBD to remap steering wheel buttons?

    Wish the steering wheel had a little thumb joystick to replicate the iDrive knob's joystick functionality so we can use that capability without leaving the wheel. Replace mode button with sport mode. Swap sides for audio/cruise control.
  2. Fuel-It replacement lines

    I'd cut the fittings out, caliper the size of their barbs, and then transplant them to equivalently-sized SAE J30R14 fuel hose. SAE J30R14T2 is even better. You can get these hose from most auto parts stores. You can use vaseline to make fitting insertion easier, or you can warm the hose with a...
  3. Visconti lpfp install???

    Having just done the LPFP recently, it seems there's a nice opportunity for designing an entirely new tophat/basket setup that goes through the fuel tank opening as a "stick". Then you push a button or pull a pin and the entire unit hinges down to sit upright in the tank. Combined with some sort...
  4. GR Supra 101: Routes to big power

    I once said I didn't want a built transmission, because I was okay with HP right around the OEM transmission torque limit. ...now I have a built trans in my car. :rolleyes:
  5. Oil/water temps. on the street

    Ideal oil temp is between 212F and about 260F. Some oils go higher.
  6. Super knock

    Pull plugs, gap to 0.020. Use a gap feeler, not a crappy ring gauge.
  7. Shaking/vibration when braking

    You got me. I was just going from memory. ✌️
  8. Shaking/vibration when braking

    I bet you one or more of the chassis height sensor brackets are broken. There's one front left and back right. I'm pretty astonished they let you take the car back with this error on the display. The front left height sensor is pointed in red, and the one on the rear looks similar. It's just a...
  9. Shaking/vibration when braking

    Does the car alert you to any codes on the screen when you start it up? Are you able to scan for codes yourself with a tool like Bimmerlink? Certainly you should be able to take any gear to red line, at which point the car will auto-shift. Note that shift RPMs may be limited until the...
  10. Shaking/vibration when braking

    Are your 1<->2 shifting issues true even in sport+manual mode?
  11. Shaking/vibration when braking

    Dealer needs to test the runout of the rotor and the runout of the wheel hub behind the rotor. Oftentimes if there is still shuddering during braking after rotor/pad change, the wheel hub itself is deformed. I don't think Toyota provides hub/rotor runout specs in the shop manual, but 0.001"...
  12. Black Stone Report

    I use 30W100 so it stays packed in the filter like a thick mayonnaise before I slap that bad mfer in there. /edit: loving these xW40 oil reports turning up squeaky clean. Repeat after me: 0W20 is for CAFE compliance.
  13. Oil filter HU 6022 Z doesnt fit

    This is the correct filter. Toyota even rebrands it as their own if you buy an "OEM" filter.
  14. Locations Without E85 - How do you get your Octane?

    Supra only has MAP. There's one pre-throttle body, and one in the manifold.
  15. Lost 20 whp with new exhaust and flex fuel kit

    If my reading is correct: OEM exhaust is 70-81mm OEM GPF section is 81mm Your new exhaust is 70mm all through I strongly suspect your performance loss is because you actually sized down on the exhaust, which is especially negative on a turbocharged vehicle. The loss of modest 8 wheel torque is...
  16. Lost 20 whp with new exhaust and flex fuel kit

    What was the temperature, DA, and IAT for each dyno session?
  17. BM3 Rough Running, Mixture too lean

    BM3 OTS maps aren't all that good. I wouldn't worry about it.
  18. Wheel Hub Assembly Removal Help

    I believe it's 17mm hex torqued to 155 ft-lbs + 90°. It's single use, so buy two more as well. For future googlers: Supra a90 rear axle nut torque
  19. Rubbing Damage Fixed With Added Benefit

    What kind of oil do you use for a trim panel delete?

    78mm studs -> open lugs -> never worry again.
